On our first day at CW, we found ourselves in the east end of the area at lunchtime. We were closest to Chownings, a sign on the front says that the dining hall is closed at lunch, but you can go to the back patio (wonder what happens when the weather is bad?).
What you find on the back patio is a CW version of McDonald's (I am NOT kidding!) You walk up to a counter and place your order....and the food is typical for McD's also! Not a lot of variety, I chose the cheeseburger/chips/soft drink for almost $12.00! If the food had been of good quality I wouldn't write this review, but the meat was gross - I ate a few bites and that was all I could deal with. So, I ended up paying $12.00 for a bag of chips and a soda!!
My advice? Plan it so that you are closer to the western end of CW near a mealtime, and go to Merchant's Square, lots of eateries there. 2nd day we at at the Cheese Shop, while I paid $10.00 for a turkey sandwich/chips/soda, at least it was of a good quality!! Or, if you want to take a backpack, just get a Subway sandwich and bring it into CW. I'm not a cheap person, but I don't appreciate paying WAY more for something, esp. when I have to order from a counter.
Other than the negative food experience, I really enjoyed my 2 days at CW, and would go back - but CW needs to re-think it's restaurant services, from the reviews I've read of the taverns on site, the eating options are very limited in CW.
